Performs powerup initialization. If initialization fails, the Current
Module Communication Status field in the DeviceNet Status
Display is set to 04. You must recycle power to recover from a
power-up initialization failure. Repeated failures may indicate a
faulty Communication Card or a faulty SMM.
•
